Basement door hinge failure on 2022 4081

[Rustymayes]

The more I get to know this rig and really see what I bought for .5 Million dollars US, the more disappointed I am. Many things are coming up that I would expect in a mass produced lower to mid range brand but the mighty Newmar? I thought I was buying a well engineered coach from the chassis to the furnishings. Clearly these are made from off the shelf parts everyone else buys from China and assembled by overworked and under paid assembly line workers. Here is another example of piss poor execution.
The basement door hinges are sturdy, I will say that but the other day I opened one of the right-side doors and Bang!, when it opened to the stop the door fell three inches! It turns out the door is held vertically in place on the hinge by a couple of very small, Too Fricking small, snap rings. There are two aluminum bushings that serve as hinge bearings which is a good plan indeed. The issue is that the weight of the door is supported by two little 5/8 inch ID X 1/16 inch thick outside snap rings, The snap rings popped out of their respective groves so the door just dropped and was caught by a cotter pin at the bottom end of the hinge bracket rod. See attached Pic.

I had to buy a snap ring plier set that was small enough to work, lift the door back into place and re install the cheesy little snap rings on Friday before the trip we took up to Alexander Valley wine country for the weekend. I thought maybe only either the top or bottom snap ring may have been engaged during assembly and rigging so it finally failed.
I made certain both were as secure as designed. This morning when I opened the door to load up to go home, BANG! The door dropped again!! Luckily I added my pliers to my tool kit that I carry in the coach.
I will be calling Newmar to see if there is an improved hinge retaining mechanism. If not, I will machine new hinge bushings that will have a sheer and jam nut in place of the crappy snap ring. I will post my fix and who knows? I may produce them and sell as an after market fix.
I noticed also that another one of my fender skirts was flopping around when I got home. The shitty cheap self tapping screws that the assemblers used backed out and fell off. I will now be replacing all of that hardware with proper nuts and bolts with locking nuts.
Again, I expect this from a $150,000 coach but not a half and million dollar machine.

Soory to hear of your experience, I did not expect this of an almost $200,000 machine either. Unfortunately, $50,000 - 1.5 million. They all seem to have problems. Hope you get this resolved quickly.

@Rustymayes , keep us posted on repair solutions. My 4081 also had the fender skirts flopping in the breeze, 1st one with only 1200 miles on it.

@GlampDaddy had a friend with the same problem on his baggage door and fixed using a hose clamp on the bushing holding it up. @ARD had this problem and we did the same fix for her.

@GlampDaddy may be able to provide a picture.

I guess you can’t expect Prevost quality on a “cheap “ Newmar

Guess I should be thankful they put the piano hinges on the Superstar baggage doors.

I think these are doors that drop a few inches when you open them to clear something - don’t recall exactly why - bottom edge of a slide maybe? So the trusty and solid steel piano hinge secured by 20 or so rivets on each side wouldn't suffice.

Here is a picture of the basement door open, and drooped. It drops to clear the bottom edge of the Slide

I have only 1 door that drops down, like @Joe Goodxrvn shows, the water bay, all others open level, the curb side slides are higher than the driver side, most of the driver side access doors are narrow and don't swing far enough out to hit the slide
